COUPLING-RING son CORRUGATED oULvrra'rs.

To all whom it may'cohcem:

Be it known that I, GEORGE \V. STonMs, a citizen of the United States, and a resident of Louisville, in the county of Jefferson and Rings for Corrugated Culverts, of which the fdllowing is a specification. My invention relates to devices for coupused for culverts, and has forits object the provision of an open coupling-ring formed of sheet metal and provided with a fastening device to clamp the "two ends of the ring together, consisting of a hook member on one end of the ring and a perforated clip on the other. end having a 'threaded eye-bolt mounted in the perforation to be secured to said hook and a nut on theithre'adedstem to draw the ends of the ring together.

My. improvement willbe described in detail hereinafter, and illustrated in the accompanying drawings, in which- Figure l is a View of two fragments of a corrugated culvert coupled by one form of my coupling-ring3 Fig. 2, an edge view of the ring before being secured on the lengths of pipe; Fig. 3, aside view of a modification showing the ring made with but a single corrugation; and Fig. at, a similar view of another modification in which two corrugations are employed.

In the drawings similar reference charac-v ters indicate corresponding parts throughout all of the views.

Corrugated metal culverts such as shown in Fig. l, and indicated by characters A and A are employed in carrying surface streams across wagon. roads, beds of electric and steam railroads, etc, and are made in standard lengths. lVhen necessary to use more than one length of the corrugated tubing to cross. a road-bed,-it has lifletofore been the practice t provide the additional lengths of.

tubes with split ends that will fit the tubular end-of anadjacent length" and provide the .split end with a threaded clamp to secure the split end in place. This construction I has not only been demonstrated to be eg'gpensiye, but in shipping the tubes theclainps are liable to be broken. or "parts lost or the split ends of the tubes broken in handling so that the use of this coupling means has been found to fbe undesirable.

My invention contemplates the employ- ,rnent ofseparable rings indicated at 1 in Specification of Letters Patent. Application filed June 2, 1909. Serial No. 499,746.

Figs. 1 and 2, l in Fig. 3, and 1 in Fig. 4,

made of the same sheet metal as the tubes,

but with the ends'of the strip left disconnccted, so, that the ring is open to admit of it being placed around the moetingend of the tube before being secured thereon.

The form shown in Figs. 1 and 2 is con; structed with two complete concave cprrugations 2, and leavinga convex corrugation 3 in the middle of the ring with the edges of the ring flared upwardly, as shown at 4. The tubes are formed with concave corrugations adjacent to each end so-' that in placing the ring shown in Figs. 1 and 2 in place one of the. corrugations 2 mates with the concave corrugation at one end of the tubes, say A, and the othcr corrugatien the cormgation at the adjacent" end of the other tube A.

To secure the ends of the coupling-ring to gether so as to make'a Water-tight joint be tween the tubes A and A, I provide a clamp 7 consisting of a hook 5, secured to one end extending lug 7, having a hol 3 9 indicates a threaded bolt slidably mount:

ed in the hole 8 and having-a loop or eye 10 on its end to engage hook 5 anda nut 11, mounted on the threaded stem that engages lug 7. i

V Vhen the coupling-ring is placed in position, as shown in Fig. 1, and the loop or eye 10 is engaged by hook 5, the ring may beclainped on the ends of tubes And A by screwing the nut- 11 up on the stem of the bolt 9, and thus form a water-tight joint and hold the two tubessecurely together, end

to end.

In the form shown inFig. 3 the ring is formed with but a single convex corruga- UOD." 12, this form hem the most economical because oii theuse ot but one-half of the,

material shown'inFig. 1, the ends 'of the When this form is used the nds of the tubes will be clamped by thp eorrugations 13 and spaced apart the with i o corrugation 14-. ..-'lhis latter form of r111 is i/the intermediate i in useful when the total lengths of the tubing l ring,

is too short to reach the length to be drained if laid end to end, the stretch permitted by the space between the ends of the tubes represented by the width of the intermediate corrugations contributing to lengthen the joined tubes the extent desired.

Having thus described my invention, what I claim, isg l 1. A pipe-coupler consisting of an open ring, a hook adjacent to one end of the "ring, an eye-bolt slidably mounted on the other end. of thering to engage said-hook, and

'means mounted on the bolttowlraw the two ends-of the ring together, substantially as shownienddescribed.

2. A pipe-coupler consisting of an open A a hook adjacent to one end of the ring, a 0 1p secured to the other end of the ring and having a perforated lu a threaded bolt slidably mounted in the ho e in the lug and having a loop on oneend to engage said hook, and a nut mounted on thebolt and engaging said lug, s'ubstantially as shown and described.

3. In combination with corrugated tubing laid end to end, an open ring of corrugated material fitting over the meeting ends of the tubing, the corrugations of the ringmating with the corrugations of the tubing,

a hook adjacent to one end of the ring, a

In witness whereof, I have hereunto set my hand in presence of two subscribing Witnesses.
